Sonic-Linux

username is: user with password: user
root password is: root

Use at own risk. All i can say is: It works here.

It might be after autologin your audio-device is not detected. Log out and back in might solve this problem.
It is not meant to be used as a daily distro, but to have a look at the audio tools available in linux
General idea is to add as many audio production tools i could think of.
Hence the KX repos are added.
Base is devuan excalibur. lxqt is the default gui. Englightenment, openbox, fluxbox and icewm are added, assuming you want to go more lightweight.
user comfort like nm-applet, bluetooth and so forth are disabled, to make it more lighweight. wireless drivers are not installed, but added as deb-packages in ~/firmware.
username is: user with password: user and root password is root.
